VapourSynth port of Gebbi's GradFun3mod | |
Based on Muonium's GradFun3 port: | |
https://github.com/WolframRhodium/muvsfunc | |
If you don't use any of the newly added arguments | |
it will behave just like unmodified GradFun3. | |
Differences: | |
- added smode=5 that uses a bilateral filter on the GPU (CUDA) | |
output should be very similar to smode=2 | |
- fixed the strength of the bilateral filter when using | |
smode=2 to match the AviSynth version | |
- changed argument lsb to bits (default is input bitdepth) | |
- case of the resizer doesn't matter anymore | |
- every resizer supported by fmtconv.resample can be specified | |
- yuv444 can now be used with any output resolution | |
- removed fh and fv arguments for all resizers | |
Requirements: | |
- muvsfunc https://github.com/WolframRhodium/muvsfunc | |
- havsfunc https://github.com/HomeOfVapourSynthEvolution/havsfunc | |
- mvsfunc https://github.com/HomeOfVapourSynthEvolution/mvsfunc | |
- Bilateral https://github.com/HomeOfVapourSynthEvolution/VapourSynth-Bilateral | |
- BilateralGPU (optional, needs OpenCV 3.2 with CUDA module) https://github.com/WolframRhodium/VapourSynth-BilateralGPU | |
- fmtconv https://github.com/EleonoreMizo/fmtconv | |

# High bitdepth tools for Avisynth - GradFun3mod r6 | |
# based on Dither v1.27.2 | |
# Author: Firesledge, slightly modified by Gebbi | |
# | |
# What? | |
# - This is a slightly modified version of the original GradFun3. | |
# - It combines the usual color banding removal stuff with resizers during the process | |
# for sexier results (less detail loss, especially for downscales of cartoons). | |
# - This is a starter script, not everything is covered through parameters. Modify it to your needs. | |
# | |
# Requirements (in addition to the Dither requirements): | |
# - AviSynth 2.6.x | |
# - Debilinear, Debicubic, DebilinearM | |
# - NNEDI3 + nnedi3_resize16 | |
# | |
# Changes from the original GradFun3: | |
# - yuv444 = true | |
# (4:2:0 -> 4:4:4 colorspace conversion, needs 1920x1080 input) | |
# - resizer = [ "none", "Debilinear", "DebilinearM", "Debicubic", "DebicubicM", "Spline16", | |
# "Spline36", "Spline64", "lineart_rpow2", "lineart_rpow2_bicubic" ] | |
# (use it only for downscales) | |
# NOTE: As of r2 Debicubic doesn't have 16-bit precision, so a Y (luma) plane fix by torch is used here, | |
# more info: https://mechaweaponsvidya.wordpress.com/2015/07/07/a-precise-debicubic/ | |
# Without yuv444=true Dither_resize16 is used with an inverse bicubic kernel. | |
# - w = 1280, h = 720 | |
# (output width & height for the resizers; or production resolution for resizer="lineart_rpow2") | |
# - smode = 4 | |
# (the old GradFun3mod behaviour for legacy reasons; based on smode = 1 (dfttest); | |
# not useful anymore in most cases, use smode = 2 instead (less detail loss)) | |
# - deb = true | |
# (legacy parameter; same as resizer = "DebilinearM") | |
# | |
# Usage examples: | |
# - Source is bilinear 720p->1080p upscale (BD) with 1080p credits overlayed, | |
# revert the upscale without fucking up the credits: | |
# lwlibavvideosource("lol.m2ts") | |
# GradFun3mod(smode=1, yuv444=true, resizer="DebilinearM") | |
# | |
# - same as above, but bicubic Catmull-Rom upscale (outlines are kind of "blocky" and oversharped): | |
# GradFun3mod(smode=1, yuv444=true, resizer="DebicubicM", b=0, c=1) | |
# (you may try any value between 0 and 0.2 for b, and between 0.7 and 1 for c) | |
# | |
# - You just want to get rid off the banding without changing the resolution: | |
# GradFun3(smode=2) | |
# | |
# - Source is 1080p production (BD), downscale to 720p: | |
# GradFun3mod(smode=2, yuv444=true, resizer="Spline36") | |
# | |
# - Source is a HDTV transportstream (or CR or whatever), downscale to 720p: | |
# GradFun3mod(smode=2, resizer="Spline36") | |
# | |
# - Source is anime, 720p->1080p upscale, keep the resolution | |
# but with smoother lineart instead of bilinear upscaled shit: | |
# GradFun3mod(smode=2, resizer="lineart_rpow2") | |
# This won't actually resize the video but instead mask the lineart and re-upscale it using | |
# nnedi3_rpow2 which often results in much better looking lineart (script mostly by Daiz). | |
# | |
# Note: Those examples don't include parameters like thr, radius, elast, mode, ampo, ampn, staticnoise. | |
# You probably don't want to use the default values. | |
# For 16-bit output use: | |
# GradFun3mod(lsb=true).Dither_out() | |
# | |
# What's the production resolution of my korean cartoon? | |
# - Use your eyes combined with Debilinear(1280,720) - if it looks like oversharped shit, | |
# it was probably produced in a higher resolution. | |
# - Use Debilinear(1280,720).BilinearResize(1920,1080) for detail loss search. | |
# - Alternatively you can lookup the (estimated) production resolution at | |
# http://anibin.blogspot.com (but don't blindly trust those results) | |

VapourSynth port of DebilinearM | |
Currently only YUV420 and YUV422 input makes sense | |
Differences: | |
- changed the cubic argument to descale_kernel, | |
so that this function is not limited to bilinear or bicubic | |
- chroma is never scaled with an inverted kernel | |
- added yuv444 argument to convert to yuv444 | |
- added arguments to fine tune the resizers | |
Usage: | |
It is recommended to use the function alias for the desired kernel: | |
DebilinearM(clip, 1280, 720) | |
DebicubicM(clip, 1280, 720, b=0, c=0.5) | |
DelanczosM(clip, 1280, 720, taps=3) | |
Despline16M(clip, 1280, 720) | |
Despline36M(clip, 1280, 720) | |
Original header: | |
DebilinearM is a wrapper function for the Debilinear and Debicubic plugins that masks parts of the frame that aren't upscaled, | |
such as text overlays, and uses a regular resize kernel to downscale those areas. It works by downscaling the input | |
clip to the target resolution with Debilinear or Debicubic, upscaling it again, comparing it to the original clip, | |
and masking pixels that have a difference greater than the specified threshold. | |

VapourSynth port of JIVTC. | |
Original script by lovesyk (https://github.com/lovesyk/avisynth-scripts/blob/master/JIVTC.avsi) | |
JIVTC applies inverse telecine in a way to minimize artifacts often seen on Japanese | |

Dependencies: yadifmod, nnedi3 | |
clip src: Source clip. Has to be 60i (30000/1001). | |
int pattern: First frame of any clean-combed-combed-clean-clean sequence. | |
int threshold (10): This setting controls with how much probability one field has to | |
look better than the other to recalculate the other one using it. | |
Since there is no point dropping a field on a still (detail loss) | |
or an action (both results will look bad) scene, keep this above 0. | |
bool draft (false): If set to true, skip recalculate step (which means keep 50% of bad fields). | |
clip ivtced: Can be used to supply a custom IVTCed clip. | |
Keep in mind that the default IVTC process gets rid of 50% of | |
bad fields which might be "restored" depending on your supplied clip. | |
string bobber: Can be used to supply a custom bobber. | |
The less information the bobber uses from the other field, | |
the better the result will be. | |
bool show (false): If set to true, mark those frames that were recalculated. | |
